So, there’s this horse race on Saturday that’s a big deal (especially if a horse named Always Dreaming wins it, as that will lead to talk of a possible Triple Crown winner and allow horseracing to grip the nation’s sports consciousness for the next few weeks). The race is scheduled to start around 6:45 p.m. We’re told this is Maryland’s biggest annual spring event (show up, and you’ll be one of about 125,000). Sounds like there’s a lot of fun to be had. The Infield opens at 10 a.m. Saturday, with the day’s racing set to begin at 10:30 a.m. at Pimlico Race Course, 5201 Park Heights Ave. $100-$110 for the infield, $40-$385 and up for elsewhere (some seats require the purchase of a two-day package that includes Friday’s Black Eyed Susan Stakes). preakness.com.
